ABB REL650 - Interlocking for Breaker-And-A-Half Diameter BH (3)

setting the appropriate module inputs as follows. In the functional block diagram, 0 and 1
are designated 0=FALSE and 1=TRUE:
• 289_OP = 1
• 289_CL = 0
• 789_OP = 1
• 789_CL = 0
• 7189G_OP = 1
• 7189G_CL = 0
If there is no second busbar B and therefore no 289 and 2089 disconnectors, then the
interlocking for 289 and 2089 are not used. The states for 289, 2089, 2189G, BC_12,
BBTR are set to open by setting the appropriate module inputs as follows. In the functional
block diagram, 0 and 1 are designated 0=FALSE and 1=TRUE:
• 289_OP = 1
• 289_CL = 0
• 2089_OP = 1
• 2089_CL = 0
• 2189G_OP = 1
• 2189G_CL = 0
• BC_12_CL = 0
• VP_BC_12 = 1
• BBTR_OP = 1
• VP_BBTR = 1
